Abstract

Based on the principles of electron currents conservation and mass conservation, this paper considers the two kinds biochemical reactions of organic aerobic oxidation and simultaneous nitrification-denitrification under the condition of aerobic degradation of municipal solid waste (MSW). Select rapid degradation cellulose (RDC), slow degradation cellulose (SDC), total sugar, fat, protein, and microorganisms as the limiting substrates, and write an aerobic biochemical reaction stoichiometric equation that can reflect the mass linkages among various substances. First-order kinetic equations were used to describe the kinetic behavior of biodegradable organics in the process of aerobic degradation, meanwhile the effects of temperature, water content, and oxygen concentration on the aerobic degradation rate of organic matter were also considered. The microorganism decay was described using a first-order kinetic equation. A model with a clear physical meaning and capable of simulating the time-varying process of aerobic degradation of MSW has been established. The robustness of the model still requires instance validation.
